In our linux-2.4 kernel tree we support the Exar ST16C554 quad UART for a board; see "drivers/char/serial.c" and look for CONFIG_SERIAL_TTTECH. > I am using serial driver from denx, and I used it successfully for other > board which had 16550 uart, and had interrupts hooked to IRQ4 and IRQ5. > The new board has 4 interrupts hooked on PC8,PC9,PC10 and PC11.

Basicly you can just do the same like we did for the TTTECH configuration; the only significant difference is that we used a shared interrupt; therefore you should NOT #define the variable CONFIG_SERIAL_SHARE_IRQ Best regards, Wolfgang Denk -- Software Engineering: Embedded and Realtime Systems, Embedded Linux Phone: (+49)-8142-4596-87 Fax: (+49)-8142-4596-88 Email: wd at denx.de Voodoo Programming: Things programmers do that they know shouldn't work but they try anyway, and which sometimes actually work, such as recompiling everything. - Karl Lehenbauer ** Sent via the linuxppc-embedded mail list.
